Electric Showers need a minimum pressure in order to work. ShowerPowerBoosters are a retrofit pump, they are designed to legally and effectively improve a poor performing electric shower. Depending on the KW power of your electric shower a SP2B or SP21S will stop a shower shutting down or running too hot because the mains pressure is (or the pressure fluctuates when someone in your house (or your neighbour), turns a tap on. A ShowerPowerBooster will always boost the pressure before it reaches an electric shower. If you have a pressure problem this is a 5 Star Solution for your problem.
A ShowerPowerBooster can legally boost the cold feed to an electric shower in full compliance with water bylaws and you need no permission to fit one. A shower power booster will always sort out a pressure problem with an electric shower but an electric shower can never deliver hot water at a rate faster than an electric shower can heat it. An electric shower will deliberately stop more flow that it can heat so if you run the shower at full cold and the flow is greater than running it at full hot then thats because the electric shower is closing a valve to stop it getting more flow than it can heat.
Fitting a Shower Power Booster is simplicity itself, remove 110mm of pipe, insert the pump, tighten the compression joints, plug it in, enjoy. You can fit a shower power booster at any angle and at any position so you can fit it away from the electric shower out of sight or next to the electric shower hidden in a wall. We have solutions for all electric showers.
Whatever pressure and flow we suggest you try a WrightChoice Shower Head which ensures you have the best shower whatever the flow and pressure you have
BOOSTING MAINS PRESSURE
Connecting a shower power booster to a mains supply is very easy and it will fit on existing pipe work. The pump is compact and needs no support, you can even fit one inside a wall cavity or under a floorboard. It can be close to or far away from the electric shower as long as its on the pipe that feeds the shower.
The maximum output of an electric shower is determined by its KW power rating and in winter because the cold water is colder then the output is less:-
7.5 KW Electric Shower 3.5 litres a minute – Single Boost SP2B should sort it.
9.8 KW Electric Shower 4.7 litres a minute – Double Boost SP21S should sort it
12.5 KW Electric Shower 6.0 litres a minute – Double Boost SP21S can sort it if problem is not severe.
If by turning the shower to cold you get more water to flow then its probably because the electric shower itself is turning down the water pressure. Simply adding pressure will cause the electric shower to reduce the pressure further to what you had before you fitted the pump.
If you do not get an increase in flow turning the shower from hot to cold, or especially if the shower is cutting out due to low pressure, then the Shower Power Booster could be the perfect solution. 15 minutes – job done – much better shower – and you have joined hundreds of other happy customers.
